Part 1. Reduction in potable water use per person

Total water withdrawal (potable and non-potable combined):

	Performance Year	Baseline Year
Total water withdrawal	1,736,757,696 Gallons	695,680,350 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	200,365,264 Gallons	184,770,960 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Period	July 1, 2018	June 30, 2019
Baseline Period	July 1, 2004	June 30, 2005

If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the water use baseline was adopted:

We have chosen to use 2005 as our baseline year for as many of the utility data credits as possible. Since we submitted our first STARS report in 2014 and used 2005 as our baseline year, we want to stick with it. This aligns with our GHG reporting as well.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	2,418	2,762
Number of employees resident on-site	4	4
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	10,487	11,695.45
Full-time equivalent of employees	2,778	2,372

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

The University of Montana really hasn't developed or implemented any water-related behavior change initiatives.

A brief description of the institution's water recovery and reuse initiatives:

UM uses non-potable water for all of our groundwater cooling systems. In Gallagher, the building that houses our College of Business, we use HVAC ground water (captured in a cistern) for irrigation. We also relocated a data center on campus that was using potable water for cooling to a new location that resulted in saving 8,409,600 gallons of water a year.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Facilities services strives to remove all pump-and-dump cooling systems whenever possible and replace them with more water-efficient cooling options.

Data source(s) and notes about the submission:

Data for potable and non-potable water use is attached. Ground water cooling and irrigation are both non-potable and include the UM-owned golf course. The only potable water is water use in buildings.
